Sheobtained the data on percentage of students passing the proficiencytest (% Passing), daily average of the percentage of studentsattending class (% Attendance), average teacher salary in dollars(Salaries), and instructional spending per pupil in dollars(Spending) of 47 schools in the state. Following is the multiple regression output with Y = %Passing as the dependent variable, X1= % Attendance, X2 = Salariesand X3 = Spending: ANOVA Referring to Table 14 - 16, which of the following is the correctalternative hypothesis to determine whether there is a significantrelationship between percentage of students passing the proficiencytest and the entire set of explanatory variables? A)H1 : At least one of betaj is not = 0for j = 1, 2, 3 B)H1 : beta0 = beta1 =beta2 = beta3 is not = 0 C)H1 : At least one of betaj is not = 0for j = 0, 1, 2, 3 D)H1 : beta1 = beta2 =beta3 is not = 0 28. TABLE 17 - 2 The following payoff matrix is given in dollars. Suppose the probability of Event 1 is 0.5 and Event 2 is 0.5. Referring to Table 17 - 2, the EVPI is A)600 B)400 C)0 D)300
